Summary
A technique based on the Galerkin approach has been developed for determination of the natural frequencies of rectangular plates with discrete masses added. The technique is applied to the rectangular plates with simply supported and clamped boundary conditions, but no difficulty exists in applying the same method to the plates of various forms with different boundary conditions. The results of this technique applied to one particular case are compared to a solution obtained by an exact method; the comparison shows the two methods to be in excellent agreement.
Übersicht
Es wird eine auf dem Galerkin-Verfahren basierende Methode zur Berechnung der Eigenfrequenzen rechteckiger Platten mit diskreten Einzel-Massen angegeben. Es werden einfach aufgelagerte und eingespannte rechteckige Platten untersucht, jedoch ergeben sich keine Schwierigkeiten bei der Anwendung derselben Methode auf Platten anderer Formen mit anderen Randbedingungen. Für einen Sonderfall werden die Ergebnisse der Berechnungen mit exakten Lösungen verglichen, wobei eine ausgezeichnete Übereinstimmung festgestellt werden kann.
